Workaround for Transferring Project Invoice to Receivables using Standard lines

Hello Experts

Anyone here had this similar challenge on moving Project Invoices to Receivables. The current setup is as below

In Receivables Auto Accounting Rule the Revenue is using Standard Lines as a Source. This causes an error when running the Import Auto Invoice

for Invoices coming from Projects as it cannot derive the revenue account string. As per discussions found on this forum, Project Billing Contracts does not support Standard Lines hence we cannot transfer the invoices if using this as source in AR.

Is there any viable workaround available to be able to transfer invoices from Projects while still retaining standard lines as source for revenue in AR?
